I recently rebuilt my carburetor with a kit I purchased from O'Reilly. They searched a product book they have but could not find the choke pulldown diaphram. Where can I locate one?

The part has the number 2F21A on it and below that it has AB. The part is off a 1972 Motorcraft 2100 carburetor which was originally installed on 1972 351 Mustangs.

I've performed serveral internet searches but have had no luck. Hopefully someone here can help.

 

Didn't reallize the choke had a diaphram. I thought it pulled off with a bimetalic spring. Did you try these guys? http://www.ponycarburetors.com/

 

I've included a picture in case I am not describing the part correctly. I took the piece off and into the auto parts store but it did not help.

 

Never seen a carb with that on there. Email that to the site I sent you and see what they say.

 

Try searching for choke pulloff diaphram on the kragen ( checker) or autozone web sites. I see several.
